Color scale is very easy to match to the test solution.
Not much room to mix reagents into solution since the test tube is almost full at that point.
I bought the Red Sea PO4 test after having a very difficult time matching colors in the Hagen and API kits. The color chart for the Red Sea kit is very close to the colors you get from the sample being tested making readings easier to determine.
The only complaing I have is that the test tube has very little rooms to mix the reagents into the sample. The stopper cannot be fully inserted or else there is no airspace left in the tube to agitate the thick #2 reagent into to test sample.
